ENGINE STARTING DEVICE.

Specification of Letters Patent.

Patented Jan. 17, 1911.

T 0 all whom it may concern:

Be itknown that I, ALBERT C. MnNcns, a citizen of the. United States,residing at Memphis, Tennessee, have invented certain new and usefulImprovements in Engine- Starting Devices, of which the following is aspecification.

This invention relates to improvements in engine. starting devices.

The main objects of this invention are:'

First, to provide an improved engine starting device in which the poweris stored by the, engine while in operation. Second, to provide animprovedengine starting device in which the power is furnished by aspring which is put under tension by a pump operated from the engine.Third, to provide an improved engine starting device having theabove-stated features in which the pump driving connections areautomatically connected and disconnected, and the spring connections areautomatically disconnected from the engine shaft when the engine isstarted. Further objects, and objects relatin structural details, willdefinitely appear from the detailed description'to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The structure described constitutes one eifective embodiment of myinvention. Other embodiments would be readily devised by those skilledin the art.

The invention is clearly defined and pointed out in the claims.

A structure constituting an effective and preferred embodiment of thefeatures of my invention is clearly illustrated in the accompanyingdrawing, forming a part of this specification, in which:

Figure 1 is a'detail plan View of a structure embodying the features ofmy invention, portions only of a motor vehicle being illustrated a showthe operative relation of the parts of an improved starting device inuse. Fig. 2 is an enlarged detail vertical section taken. on a linecorresponding to line 2-2 of Fig. 1: Fig. 3 is an enlarged detailsection taken on a line corresponding to line I into engagement with theclutch member on 33 of Fig. 1, showing details of the drum 12. Fig. atis an enlarged detail plan showthe disconnecting n'ieclianism of theimprovement shown, parts being broken away to better illustrate the formand arrangement. Fig. 6 is an enlarged detail taken on a linecorresponding to line 66 of Fig. 5.

In the drawings, similar reference charac ters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents the frame of a motor vehicle and2 the crank shaft of the engine, the engine not being here illustrated.Suitably supported upon the frame is a fluid tank 8 and a cylinder 4.This cylinder-is connected at its inner end to discharge into the tankthrough a suitable valved opening, the valve 5 being shown inconventional form.

Within the tank 3 are pumps 6, also shown in conventional form, a seriesof four pumps being shown, all connected to the same crank shaft 7.These pumps are con; nected to deliver to the inner end of the cylinder4 through the passage 8.

ithin the cylinder is a plunger 9, which is forced outwardly by thepumping of the 'fluid into the inner end of the cylinder. An

actuating spring 10 is preferably arranged within the cylinder, as shownin the draw ing, one end being connected to the plunger, and the otherat. the inner end of the cylinder, as at 11. On the shaft 2 is a drum12, the drum being revolubly mounted on the shaft and connected to theplunger by means of the cable 13. This cable is arranged over a guidepulley 14.. As the piunger is forced outwardly by the pumping of thefluid into the cylinder, the drum is rotated to wind up or take up theslack of the cable by means of the spring 15, one end of which" issecured to the frame at 16, and the otherto the hub of the pulley, at17.

A clutch is provided for securing the drum to the shaft, the clutchmember 18 being slid- =ably connected to the shaft by the 9 line 19 sothat it is revolved with the sha while the drum is provided with aco-acting clutch member 20. The clutch member 18 is thrown foroperation, as is also the rod 23 through.

which the valve 5 is controlled. The clutch rod is shifted by theplunger.

is preferably automatically disengaged by providing the drum with a trip24adapted to engage the trip lug 25 on' the lever 21 as the drumrevolves to shift the clutch mem- The pumps are preferably driven fromthe shaft 2,the driving means comprising a driving wheel26 on the shaftand a driven wheel 1 27, which is supported to be shifted into and outof driving engagement with the driving wheel, thus connecting anddisconnecting the driving connections of the pump.

The wheel 27 is mounted on a shaft 28, which is connected through thegears 29 and 30 to the pump crank shaft 7. .The means for starting thedriving wheel, and the automatic engaging and disengaging means thereforare shown in Figs. 4, 5 and 6.

The bearing 31 for the swinging end of thesh'aft 28 is preferablyspherical in form, as lllustrated, and slidably mounted in the bracket32. This bearing is held yieldingly outward to hold. the wheels inengagement by means of the'spring 33, which engages the arm 34 on thebearing engaging member 35, see Fig. 5. A bell crank lever 36 is mountedso that 'one'arm engages the arm 34 on themember 35. This lever isactuated to shift the member-35 by'means of a trip rod 38, one endofwhich extends into the cylinder to be engagedby the plunger andactuated to shift the lever 36, thus disengaging the driving connection.

The rod 38 is preferably arranged through one arm of the lever, asillustrated, and provided with a spring 39, one end of which lever andthe other thereby providing a yielding connection. The lever is held ineither position by means of a pair of catches 41 and 42, the catch 41being adapted to hold the parts in their driving relation while thecatchr42 holds the parts in their disengaged relation. The catch 41 isoperated by the trip 40, which engages the cam 43 as the trip The catch42 is provided with a tripping cam 44, which is engagedby the trip 45on' the rod as it is returned by the spring 46 when the plunger isreleased through the opening of the valve 5, the plunger being returnedto its initial positionthroughthe actuating spring 46, as will beobvious. This arrangement secures a means for automatically connectingand disconnecting the driving connections for the pump. The clutch forthe drum to the shaft is also automatically disconnected, so that thespring is always under tension to sup port the engine, and when theengine is started through the releasing of the plunge] to permit theescape of the, fluid from the cylinder, the pump connections are engagedso that the springis r'e-set, and it is only necessary fortheoperator'to' engage the said shaft; a to said drum a clutch forconnecting said clutch of the drum and release or open the valve, thevalve being closed after the engine 15 started. a H

I have illustrated and described my improvementsin the form preferred byme, although I am aware that it is capable of having considerablemodification in .structural details, and I desire to be understood asclaiming the same specifically in the form illustrated, as well asbroadly within the scope of the'appended claims.
